Radio-locating mid-range air-to-air missiles R-27 represent or constitute the main weapons of Ukrainian russian MiG-29 fighters (before the war about 40 in active service) and Su-27 (before the war 34 in service). Despite the fact that Ukrainian aircraft seldom participated in typical air combats, they frequently attacked with the aid of these missiles enemy ammunition circulating or maneuvering missiles. After 2 and a half years of war, supplies of this weaponry, despite supplies from 3rd countries, are surely exhausted.
